Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Call (830) 251-4560 and we’ll schedule a time that fits your week, not ours.
Why Flint Chimney Sweep Is Belmont’s Preferred Chimney Repair Company
We’re part of the Garrison Partners family, founded in 2002, and we operate under the Garrison Standard: a written price before work starts, background-checked and uniformed technicians on every call, and a guarantee we don’t hedge on. Homeowners in Belmont tell us the same thing, they’ve been burned by chimney companies that quoted one number on the phone and a different one at the door. That doesn’t happen with us because the number you approve is the number on the invoice.
Hank Delano and our crew know Belmont’s housing stock, not just chimneys in general. We know a 1920s colonial near Belmont Center has different failure points than a 1950s split-level off Trapelo Road, and we know what a camera inspection is actually looking for in each. Our response time to Belmont runs two to four business days for non-emergency repairs, and our phones are answered by a live person around the clock, even Saturday night when you’re staring at a water stain on the ceiling.
Chimney Liner Installation in Belmont
Chimney Liner Installation in Belmont means replacing the inner liner that channels smoke safely out of the house, and it’s the repair we recommend most often for older center-chimney homes near Belmont Center and the Hill Estates. Many of those 1920s – 40s colonials were built with unlined or parged flues. The parging breaks down over decades, the flue no longer protects the framing around it, and the result is a fire and carbon monoxide risk that a standard sweep cannot fix.
We install liners sized to the specific appliance, whether it’s a wood stove, an oil burner, or a natural gas furnace. A full relining in Belmont typically runs $2,400 – $5,500 depending on flue height, access, and whether we’re converting from an unlined flue or replacing a cracked clay tile liner. The system we specify depends on the job: HeatShield for resurfacing an existing flue that is structurally sound, DuraFlex for a continuous stainless liner where the old flue is compromised, and Copperfield components for chase covers and termination caps.
HeatShield resurfacing for older flues
When the flue tile is cracked but the chimney structure itself is solid, we can often use a HeatShield cerfractory system to resurface the inside instead of demolishing the flue. This matters in Belmont because so many center-chimney homes have flues boxed in between finished walls, making a full liner pull far more invasive. HeatShield restores a continuous, insulated surface and carries a manufacturer’s warranty on the materials.
Full stainless relining with DuraFlex
When an older Belmont chimney has never had a liner, or the existing clay tile is broken beyond resurfacing, we install a continuous stainless steel liner. DuraFlex is our standard specification for these jobs; it’s a flexible, UL-listed liner that handles high heat and resists the acidic condensate that modern gas appliances produce. We size the liner to the appliance, not the other way around, and the installation is done without tearing open finished walls in most cases.
Chimney Flashing Repair in Belmont
Chimney Flashing Repair in Belmont addresses the metal where the chimney meets the roofline, and it’s the most common repair we make on mid-century side chimneys in Waverley, Cushing Square, and along Concord Avenue. Flashing that was installed in the 1950s and 60s is now 60 to 75 years old, and when it fails, water gets behind it, freezes and thaws through a New England winter, and spalls the brick and mortar around it. The repair involves removing the old flashing, cutting a reglet into the mortar joint, installing new step and counter flashing, and sealing everything with a high-grade sealant.
Flashing replacement in Belmont runs $425 – $1,800 depending on how much flashing is involved, whether the crown also needs work, and how difficult the roof access is. If you’re seeing water stains on the ceiling beside the chimney or damp brick after a rainstorm, flashing is the first thing we check because it’s the most affordable fix with the biggest payoff. We don’t recommend a roofer for chimney flashing. Roofers flash roofs; we flash chimneys, and that distinction matters when the leak is at the mortar joint, not the shingle line.
Step flashing and counter flashing replacement
Step flashing is the L-shaped metal woven into the shingles as they rise up the chimney. Counter flashing is the second layer embedded into the chimney mortar joint that covers the top of the step flashing. Both pieces have to come out and go back in together or the repair won’t hold through one Belmont winter.
Crown sealing and crack repair alongside flashing
On side chimneys, a cracked crown usually works together with failed flashing to let water in. If the camera shows spalling at the crown’s edge, we’ll recommend repairing the crown at the same time as the flashing, because fixing one without the other leaves the same leak path open. Crown repair in Belmont adds $350 – $800 to a flashing job depending on how much of the crown has to be rebuilt.
Trusted Brands We Service in Belmont
We service and install professional-grade chimney materials from brands Belmont homeowners can verify independently, not just take our word on. HeatShield and DuraFlex are our most common liner specifications for Belmont’s older housing stock. We use Famco and Copperfield components for dampers, caps, and termination hardware. When a part needs replacing, we keep common sizes stocked for fast turnaround across our Belmont service area, so you’re not waiting a week on a backordered damper plate while winter rain keeps coming in.
Common Chimney Repair Problems We See in Belmont Homes
Belmont’s two dominant housing eras produce two different sets of problems. Knowing which one applies to your house, not just “old chimney advice,” is what a camera inspection is for.
- Cracked crowns and failed flashing on mid-century side chimneys: the 1950s – 60s ranches and split-levels near Waverley and Cushing Square often have side-vent chimneys with thin, spalling crowns. Water gets past the crack, freezes and thaws through the winter, and the brick and mortar spall away. Flashing and crown work together, and we repair them together.
- Unlined or degraded parge flues in center-chimney colonials: near Belmont Center, the 1920s – 40s homes frequently have center chimneys with flues that were never lined or were parged decades ago. When the parging breaks down, the flue doesn’t protect the framing around it, and that’s a fire safety issue, not a cosmetic one.
- Rusted or seized damper plates: on mid-century side chimneys and older homes alike, dampers rust shut, which traps combustion gases in the flue and makes the fireplace hard to use. A seized damper also hides creosote buildup that a surface-only sweep cannot reach.
- Offset smoke chambers collecting creosote out of reach: center-chimney colonials often have offset smoke chambers that a standard brush can’t fully clean. Second- and third-degree creosote builds up there, and that’s exactly the kind of thing a Level 2 camera inspection finds before it becomes a chimney fire.

FAQs About Chimney Repair in Belmont
If you can see spalling brick, water stains on the ceiling beside the chimney, or white efflorescence on the masonry, the damage is already active and waiting makes it more expensive because freeze-thaw cycles compound it. If the only issue is a cosmetic crack in the crown with no interior water signs, it can often wait until spring. The only way to know for sure is a camera inspection we can run in under an hour. Call (830) 251-4560 and we’ll schedule a time.
A Level 2 inspection is a camera scan of every flue from the firebox to the termination cap, looking for cracked tiles, gaps, creosote buildup, and hidden damage a standard brush-pass sweep cannot see. You need one after a chimney fire, before buying or selling a home, or when a home has changed appliances or fuel type. In Belmont, we also recommend it when you own a center-chimney colonial and you’ve never seen the inside of the flue because so many of those homes were built unlined.
Yes. Every repair gets a written price before any work starts, and that’s non-negotiable, not a marketing line. For flashing, we quote a flat range based on the problem you describe and confirm it with the camera inspection. For liners, we quote a fixed number once we’ve measured the flue. The number on the invoice is the number you approved.
Expect a camera inspection to show parged or unlined flue walls that no longer protect the framing around them, and expect the repair to involve a flue relining rather than a simple sweep. We’ll specify a HeatShield or DuraFlex system based on what the camera shows, and you’ll get a written price before anything is ordered. The work itself typically takes one long day or two half-days in a Belmont colonial.
We do flashing repair as a core service, and we recommend a chimney company, not a roofer, for chimney flashing because the failure is at the mortar joint, not the shingle line. Roofers don’t cut reglets into brick or match the mortar we’re already repairing. The flashing is part of the chimney system, and we repair it as such.
